globus_memory_init (3) - Linux Manuals
NAME
Memory Pool -
Functions
globus_bool_t globus_memory_init (globus_memory_t *mem_info, int node_size, int node_count)
Initialize memory pool.
void * globus_memory_pop_node (globus_memory_t *mem_info)
Retrieve a memory item from a pool.
globus_bool_t globus_memory_push_node (globus_memory_t *mem_info, void *buffer)
Return a memory item to the pool.
globus_bool_t globus_memory_destroy (globus_memory_t *mem_info)
Destroy a memory pool.
Detailed Description
The globus_memory abstraction implements a memory management pool for groups of same-sized data items.
Function Documentation
globus_bool_t globus_memory_destroy (globus_memory_t *mem_info)
Destroy a memory pool. Free all the memory associated with the memory management structure. For every call to globus_memory_init() there should be a call to globus_memory_destroy() or else memory will leak.
globus_bool_t globus_memory_init (globus_memory_t *mem_info, intnode_size, intnode_count)
Initialize memory pool. Initialize the globus memory management structure.
Before using any functions associate with a memory structure this function must be called.
Parameters:
-
mem_info The memory management datatype
node_size The size of the memory to allocated with each pop.
node_count The initial number of nodes allocated with the memory management structure. If it is exceeded more will be allocated.
void* globus_memory_pop_node (globus_memory_t *mem_info)
Retrieve a memory item from a pool. Pop a chunk of memory out of the memory management structure. Similar to malloc(). When no longer using this item, return it to the pool via globus_memory_push_node().
globus_bool_t globus_memory_push_node (globus_memory_t *mem_info, void *buffer)
Return a memory item to the pool. Push a chunk of memory back into the memory management structure. Similar to free().
